Marking a node in the subcluster as inactive

ThinLinc

Hi,

We have a thinlinc HA setup running in cluster mode with 2 nodes in the cluster

[/vsmserver/subclusters/default]
agents=abc.com def.com

[/vsmserver/HA]
# Enable HA operations by setting this to 1.
enabled=1

# A space-separated list of the nodes in the cluster
nodes=abc.com def.com

Now, we have a scheduled reboot of one node abc.com in the coming days. So, what I wanted is that from now till the day of reboot all the sessions get created in another node i.e def.com.

Normally you’d mark one server (thats up for a reboot) for “out-of-service” - so existing sessions on it gets time to finish - but no new ones are started. Does Thinlinc support that? (it’s like you do with slurm, and kubernetes nodes)

Is this possible and how ? that too without affecting my running sessions on abc.com node ?

Hello @Aman,

Yes, this is possible! Simply remove abc.com from the agents= configuration on both HA nodes, and restart vsmserver on both. This will keep any already running session on that agent, but prevent new sessions from being created on abc.com

See https://www.cendio.com/resources/docs/tag/config_cluster.html#stopping-new-session-creation-on-select-agents-in-a-cluster

Kind regards,
Martin
